Review Comment:
Thanks @cloud-fan for the suggestion. I have updated the PR to use the
existing `SparkStringUtils.isBlank(...)` utility instead of introducing a new
helper and restored the corresponding imports. Using the existing utility
provides broader whitespace handling via `String.isBlank`, as you noted.
Could you please take another look when you have a chance? Thanks!
